When setting value, the power supply of fluid pump motor, electric motor starting rotation are connected.Such as under the small traffic conditions of fluid, once there is fluid
Outflow, pump startup, but because the discharge of fluid is smaller, manifold pressure moment can be made to become larger, motor is shut down at once;With small stream
The fluid of amount continues to flow out, and makes pump startup, and so cycle causes the frequent starting of pump, can be damaged to motor.
However, existing fluid pump still has some shortcomings:Due to needing to install pressure in the pump housing of fluid pump
Power switchs and check-valves, and to complete control to fluid pump, and the space in the pump housing is very limited, so install pressure switch and
Check-valves will undoubtedly increase the structure complexity of fluid pump, the manufacture difficulty and manufacturing cost of larger fluid pump.
In addition, existing as Chinese invention patent CN201210321001.7 discloses a kind of water-aspirator pressure sensor (pressure

When work, water enters from the first through hole of shell lower end, and the pressure of water forces flexible sheet to generate toward magnetic core side
To raised deformation, the deformation of the flexible sheet pushes magnetic core up to move and compressed spring, because magnetic core deviates inductance coil
Displacement, magnetic linkage are reduced, and the inductance value of inductance coil is caused also to reduce;The actual pressure that pressure detection circuit calculates water outlet accordingly is big
It is small, export feed pump to provide corresponding control signal.That is, disclosed in patent of invention CN201210321001.7
Scheme is to deviate the displacement of inductance coil under flow action using magnetic core to obtain the inductance value of inductance coil in the second vessel
Situation of change, and then the actual pressure size of water is calculated according to this inductance value situation of change by pressure detection circuit again.
However, the water-aspirator pressure sensor plan disclosed in foregoing invention patent CN201210321001.7 still has not
Foot place:Due to needing inductance coil to be arranged in the second vessel of water-aspirator pressure sensor and by the lead-out wire of inductance coil
It is pierced by out of inductance sleeve the second vessel and is electrically connected with pressure detection circuit, this will make adding for water-aspirator pressure sensor
Work difficulty increases, and reduces the processing and manufacturing efficiency of sensor;In addition, due to needing by the shifting between inductance coil and magnetic core
Position obtains the inductance value situation of change in the second vessel, and after inductance value is tested out, then goes to judge pressure, inductance ratio
More sensitive, the coherence request of magnetic is problematic, and technique is bad does.
